  • Which wouldn’t have the potential if the larger sun didn’t form first to create the gravity to allow the rest to form.

    This is simply incorrect. The gravitational potential of the body would be there regardless of what else is going on around it. And either way, the OP’s question was not about some hypothetical where the sun doesn’t exist, it’s about where energy came from in the real world.

    Star != Sun is just pointlessly pedantic. You’re not trying to learn anything, just be a smartass.

    ? The OP’s question was literally “is there energy on earth that didn’t come from the sun.” I am not the one being pedantic here.


  • Nuclear materials were formed in supernovas. They wouldn’t exist in the first place without a star.

    Well, yeah, sure. But that star is not the Sun.

    Earth wouldn’t have coalesced without the sun in the middle. Otherwise we’d still be a gas blob.

    I mean, sure? It wouldn’t be a gas blob, but it would be a very different system. But that still has nothing to do with it – even if the gravity of the sun influences how the earth coalesces, it’s still not where the thermal energy of the core came from. That came from the potential of the dust itself.











  • Everyone is talking about dominant and recessive genes, so I just want to clarify a couple things.

    The way your body directly uses genes is as a blueprint to construct proteins. Your cells are always producing proteins from the genes in all your chromosomes. It has complex ways of regulating how much of each it produces, but your body doesn’t care what chromosome it’s coming from. Once an embryo is fertilized, there’s really no distinction between “mom” chromosomes or “dad” chromosomes, as far as the embryo and its protein machinery are concerned.

    “Dominant” and “recessive” characterization is about how those proteins affect your body at the macro scale, not whether your body actually uses the gene and produces its proteins – it always does that. For example, brown hair is a dominant trait, and blonde is recessive. But this is because producing any amount of brown pigment will make your hair brown, regardless of what other pigments you’re making, simply because it’s darker. Literally the same as combining blonde and brown paint. It has nothing to do with whether the genes are actually being expressed – the brown hair gene doesn’t stop the blonde hair gene from making its pigments.
